The trick is to remember that tvtropes is an encyclopaedia which is designed to be hard to use, with its practice of hiding simple concepts behind obscure film references. Don’t try to understand any of the articles; just try to learn enough to address whatever led you into there in the first place.

I would worry about what kind of cans you have to keep in a freezer, and what the sudden warming from his body heat and the open door is about to do to them. If we’re still in TV-Tropes mode, think of it as a small version of an Earth-Shattering Kaboom.

Did one of them at least disarm him of his laser sword by taking it when he was down for the count? So he can’t cut his way out later instead of freezing to death like he should? No? I don’t see anyone holding it, so they probably left it. Pretty sure there’s a trope for that, Idiot Ball maybe.

In the last scene it was lying to the right of the doorway, maybe just outside the swing of the door. In his haste to slam it shut, Walske probably didn’t take note of it. So it is either lying on the floor outside the freezer, in which case the question becomes: who gets to wield it?, or, it got pushed inside by the swinging door and is lying next to the now not-so-melancholy Dane.
